判斷題
Each of these vlans has one host each on its port SVI on vlan 1 - ip 192.168.1.11 with snm Switch B - Ports 3， 4 connected to ports 3 and 4 on Switch A Port 15 connected to Port on Router. Tasks to do 1. Use non proprietary mode of aggregation with Switch B being the initiator -- Assumed use LACP with B being in Active mode 2. Use non proprietary trunking and no negotiation -- Assumed use switchport mode trunk and switchport trunk encapsulation dot1q 3. Restrict only to vlans needed -- Assumed either vtp pruning or allowed vlan list. vtp pruning command did not seem to work on the simulator so landed using allowed vlan list 4. SVI on vlan 1 with some ip and subnet given 5. Configure switch A so that nodes other side of Router C are accessible -- Assumed this to mean that on switch A default gatway has to be configured. 6. Make switch B the root -- Could not get this to work. Exam hung when I tried the command spanning-tree vlan 1，21-23 priority 4096
答案：正確

Acme is a small shipping company that has an existing enterprise network comprised of 2 switches；DSW1 and ASW2. The topology diagram indicates their layer 2 mapping. VLAN 40 is a new VLAN that will be used to provide the shipping personnel access to the server. For security reasons， it is necessary to restrict access to VLAN 20 in the following manner： - Users connecting to ASW1’s port must be authenticate before they are given access to the network. -Authentication is to be done via a Radius server：- Radius server host： 172.120.39.46-Radius key： rad123 - Authentication should be implemented as close to the host device possible. - Devices on VLAN 20 are restricted to in the address range of 172.120.40.0/24. - Packets from devices in the address range of 172.120.40.0/24 should be passed on VLAN 20. - Packets from devices in any other address range should be dropped on VLAN 20. - Filtering should be implemented as close to the server farm as possible. The Radius server and application servers will be installed at a future date. You have been tasked with implementing the above access control as a pre-condition to installing the servers. You must use the available IOS switch features.

VLAN Trunk Protocol （VTP） reduces administration in a switched network. When you configure a new VLAN on one VTP server， the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products. There is a Lab（about VTP） in the cisco CCNP BCMSN 642-812 exam. Requirements： These are your specifc tasks： 1. Configure the VTP information with the distribution layer switch as the VTP server 2. Configure the VTP information with the access layer switch as a VTP client 3. Configure VLANs on the distribution layer switch 4. Configure inter-VLAN routing on the distribution layer switch 5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future. 6. All VLANs and VTP configurations are to completed in the global configuration To configure the switch Click on the host icon that is connected to the switch be way of a serial console cable.

topology exhibit： You work as a network engineer at . is a large international company with offices on all continents. You work at the Chicago Office. Your boss at ，Miss ，has asked you to install a Catalyst 3500 to provide for another 24 users. Your instructions are as follows： * install it in an IDF * extremely import to have the proper configuration of the Catalyst before it is placed into the product information * it should not participate in VTP * it should forward VTP advertisements that are received on trunk ports * all nontrunking interfaces， Fa0/1 to Fa0/24） should immediately to the forwarding state of the Spanning tree. * configure all Fast Ethernet ports （the user ports） such as they are nontrunking. * the fastEthernet interfaces 0/12 through 0/24 should be placed in VLAN 20

Network topology exhibit： 3 configuration exhibit： You work as a network technician at . is a large international company with offices in the US and in Europe. You work at the New York Office. Recently a new switch block with multiple VLANs configured were added to the Barcelona LAN. Your boss at， Miss， tells you that the personal at the Barcelona office failed to document the spanning tree topology during installation. She gives you a plane ticket to Barcelona and orders to provide a baseline of configuration information in regard to the switch block spanning tree topology. Two days later you arrive at the Barcelona office. You study the network topology carefully， see exhibit. Then you connect to the 3 switch； issue the show spanning tree command. Please refer to the exhibit for the output. You are then required to answer the scenario questions using the information that is available.
